1-2 HANDLING THE MOTHERBOARD

To avoid damage to your Motherboard, follow these simple rules

while unpacking:

Ø Before handling the Motherboard, ground yourself by grasping

an unpainted portion of the system's metal chassis.

Ø Remove the Motherboard from its anti-static packaging. Hold

the Motherboard by the edges and avoid touching its

components.

Ø Check the Motherboard for damage. If any chip appears loose,

press carefully to seat it firmly in its socket.

Warning: Do not apply power if the Motherboard appears

damaged. If there is damage to the board, contact your

dealer immediately.

1-3 ELECTROSTATIC DISCHARGE PRECAUTIONS

Make sure to ground yourself before handling the Motherboard or

other system components. Electrostatic discharge can easily

damage the components. Note that you must take special

precautions when handling the Motherboard in dry or air-conditioned

environment.

To protect your equipment from electrostatic discharge, take the

following precautions:

Ø Do not remove the anti-static packaging until you are ready to

install.

Ø Ground yourself before removing any system component from its

protective anti-static packaging. (To ground yourself, grasp the

expansion slot covers or other unpainted portions of the computer

chassis.)

Ø Frequently ground yourself while working or use a grounding strap.

Ø Handle the Motherboard by its edges and avoid touching its

components.

anti-static packaging until you have made the following

preparations.

2-1 PREPARATIONS

Gather and prepare all the following hardware equipment to

complete the installation successfully:

1. Slot 1 processor with built-in CPU cooling fan (boxed type).

Note: This Motherboard supports non-boxed type CPUs. The

heavier CPU cooling fan requires the installation of a CPU

support stand.

2. DIMM memory module

3. Computer case and chassis with adequate power supply unit

4. Monitor

5. PS/2 Keyboard

6. Pointing Device (PS/2 mouse)

7. Speaker(s) (optional)

8. Disk Drives: HDD, CD-ROM, Floppy drive…

9. External Peripherals: Printer, Plotter, and Modem (optional)

10. Internal Peripherals: Modem and LAN cards (optional)

2-2 UNPACKING THE MOTHERBOARD

When unpacking the Motherboard, check for the following items:

u The SY-6BA+ III 82440 BX AGP/PCI

Motherboard

u This User’ s Manual

u The Installation CD-ROM

u The CPU Retention Set

u One IDE Device Flat Cable

u One Floppy Disk Drive Flat Cable

Warning: Do not unpack the Motherboard from its anti-static

packaging until you are ready to install it.

Like most electronic equipment, your Motherboard may be damaged

by electrostatic discharge. To avoid permanent damage to

components ground yourself while working by using a grounding

strap. Otherwise, ground yourself frequently by touching the

unpainted portion of the computer chassis to drain the static

charges.

Handle the Motherboard carefully, holding it by the edges.

You are now ready to start the installation.

2-3 INSTALLATION GUIDE

We will now begin the installation of the Motherboard. Please follow

the step-by-step procedure designed to lead you to a complete and

correct installation.

Warning: Turn off the power to the Motherboard, system

chassis, and peripheral devices before performing any

work on the Motherboard or system.

BEGIN THE INSTALLATION

Step 1. CPU Installation

Your SY-6BA+ III motherboard comes with a CPU retention set kit.

The retention set is used to hold the processor attached to the Slot 1

CPU connector on the motherboard.

Mark your CPU Frequency:

Record the working frequency of

your CPU that should be clearly marked on the CPU cover.

FSB 66MHz

266MHz (66 x 4.0) 333MHz (66 x 5.0) 400MHz (66 x 6.0)

300MHz (66 x 4.5) 366MHz (66 x 5.5) 433MHz (66 x 6.5)

FSB 100MHz

350MHz (100 x 3. 5) 450MHz (100 x 4.5) 550MHz (100 x 5.5)

400MHz (100 x 4.0) 500MHz (100 x 5.0) 600MHz (100 x 6.0)

Hardware Setup SY-6BA+ III

Follow these instructions to install your Slot 1 processor correctly.

Ø Retention Module

1. Open the two sides by folding them up.

2. Push the locks on top of the CPU inward.

Hardware Setup SY-6BA+ III

10

3. Insert the CPU into the retention module. The CPU fits in the CPU slot

in only ONE way, do not try to force it in.

4. After completely inserting the CPU, push the two locks on top of the

CPU outward. Now your CPU is ready for use.

To remove the CPU, press the two notches on top of the CPU

inward. Now press the two slides on the retention module down

and remove the CPU.

Hardware Setup SY-6BA+ III

11

Note: Installing a heat sink and cooling fan on top of your

CPU is necessary for proper heat dissipation. Failing to

install these items may result in overheating and possible

burn-out of your CPU.

Step 2. CPU Fan Installation

Your Slot 1 processor kit comes with a cooling fan. Mount the fan on

the processor according to the instructions provided by the

manufacturer. The fan is a key component that will ensure system

stability. The fan prevents overheating, therefore prolonging the life

of your CPU.

Note: Remember to connect the fan to the appropriate power

source.

Hardware Setup SY-6BA+ III

12

Step 3. SDRAM Memory Module Installation

This Motherboard features 4 x DIMM Banks for 168-pin 3.3V

unbuffered and registered DIMM modules. Your board comes with

four DIMM sockets, providing support for up to 1GB of main memory

using DIMM modules from 8MB to 256MB. For 66MHz front side bus

CPUs use 12ns or faster memory; for 100MHz front side bus CPUs

use 8ns (100MHz, PC100 compliant) memory.

Note: (1) 256 MB memory modules available on PC registered DIMM only.

(2) Always install memory modules in the order prescribed in this table.

(3) Do not install unbuffered and registered memory modules together.

Important: It is of prime importance that you install DIMM modules

as outlined in the table above in order to preserve signal integrity on

100MHz front side bus systems.

Step 4. IDE Device Installation (HDD, CD-ROM)

This Motherboard offers two primary and secondary IDE device

connectors (IDE1, IDE2.) It can support up to four high-speed HDD

or CD-ROM.

Connect one side of the 40-pin flat cable to the IDE device (HDD or

CD-ROM) and plug the other end to the primary (IDE1) or secondary

(IDE2) directionally keyed IDE connector on the Motherboard.

This Motherboard can support up to four HDDs.

Step 5. Floppy Drive Installation

The system supports 5 possible floppy drive types: 720 KB, 1.2 MB,

1.44 MB, 2.88 MB, and LS-120. In addition, this Motherboard

supports a 3-mode (720KB/1.2MB/1.44MB) floppy commonly used

in Japan.

Connect one side of the 34-pin flat cable to the floppy drive and plug

the other end to the floppy drive connector on the Motherboard.

This Motherboard can support up to 2 floppy drives.

header on the Motherboard.

4. Turbo LED

Connecting the 2-pin Turbo LED cable to the corresponding Turbo

LED header will cause the LED to light whenever the system is in

Turbo mode.

The manufacturer has permanently set this Motherboard in Turbo

mode due to most hardware and software compliance to turbo

mode.

5. IDE LED

Attach the 2-pin IDE device LED cable to the corresponding IDE

LED header on the Motherboard. This will cause the LED to lighten

when an IDE (HDD, CD-ROM) device is active.
